Cinnabar Fields

He regulates the Three Luminaries (sanguang), and the Four Numina (siling) are to his sides he maintains his thoughts on his Cinnabar Field and on the Purple Chamber of the Great One (Taiyi). ... 

Central Scripture mentions the Yellow Court, the Cinnabar Field, and the Purple Chamber, i.e., three of the four terms found in the two epigraphs of 165 CE. The Scripture of the Yellow Court mentions the Hut, the Yellow Court, and the Cinnabar Field in one of its two versions, and all four terms in the otherC... 

Circulate the purple huizi) and embrace the yellow baohuang) so that they enter the Cinnabar Field ... 

Here the two pneumas are circulated and guided to the upper Cinnabar Field, while the Gate of Life (or Yang Gate) in the lower Cinnabar Field is visualized as irradiated by a light issuing forth from the kidneys (the Abyssal Chamber). 

See Laozi zhongjing, sec. 26 If you want to practice the Dao, you should first of all pass through the viscera and see their deities. We have also met earlier in this chapter a similar term used in relation to the Cinnabar Fields in one of the two inscriptions dating from 165 CE. 

Because the pH shifts to lower values at higher temperatures, the solubility of mercuric sulfide increases when such waters cool down. The deposition of cinnabar takes place, however, by mild oxidation and partial neutralization with carbon dioxide presumably delivered by telluric water (70, 71). The emplacement of cinnabar and other associated sulfides depend on the porosity of the rock where such deposits are being formed, the temperature and thermal gradient of the geothermal field, and the composition and extension of the heated rocks (14).

Merrifield (1846) cites several authors who describe a hard red mineral called amatito (q.v) or Lapis amatito. She does not believe that these terms refer to ciimabar although Borghini (1584), for example, does. Yii (1955) records that ciimabar was also known as Chensha cinnabar, from the name of a production site Chenzhou, Hunan Province, China, and Field (1835) names other sources which geologically are unlikely to contain cinnabar deposits.
